I have a friend on here that had some head work done on here by another Friend and he's running low low 11's or even High 10's on the motor with what many racers on here would consider a "broomstick" for a cam. Extremely impressive running car/engine.

Smaller than the one I'm asking about

Just general opinions from anyone that's running one or something similar with at least 493 cubes and pump gas.

Was thinking about a small Ultradyne 255/259 with the .4033 Endurance lobes

Got a motor project in mind

Thanks!
